DAMASCUS, Va. (AP) — An emergency official says authorities believe the driver who plowed into dozens of hikers marching in a Virginia mountain town parade suffered from a medical condition and did not cause the crash intentionally.

The director of emergency management for Washington County says authorities do not have a formal confirmation or any specifics on the condition. But based on the accounts of officials and witnesses on the scene, Pokey Harris says they're confident the issue was medical and the crash unintentional.

In what witnesses called a frantic scene, about 50 to 60 people suffered injuries ranging from critical to superficial during Saturday's parade in Damascus. No fatalities were reported.

Harris says two people were kept at hospitals overnight, but their injuries were not critical as of Sunday.
